Abstract

Aspects of a method and system for Ethernet and multimedia functions into a LAN subsystem are provided. In this regard, an integrated network interface which may comprise one or more Ethernet interfaces, and one or more high definition (HD) multimedia interfaces may be enabled to transmit and/or receive HD multimedia content over a network. Audio/Video Bridging and/or Audio/Video Bridging extensions may be utilized for the transmission and/or reception of HD multimedia content over a network. The integrated network interface may be enabled to transmit and/or receive physical layer signals adhering to protocols such as Ethernet and DisplayPort and may be configurable to select the type of signals to be transmitted or received. In this regard, aspects of the invention may enable converting Ethernet frames to DisplayPort micro-packets and visa-versa.
